Description

BACKGROUND OF THE INVENTION

The present invention relates to a method of power generation and its apparatus utilizing gravitation force and buoyancy, wherein a bigger out-put force than in-put can be obtained by adding to the in-put power the force generated by the actionof gravity and buoyancy.

Previously, many methods and/or apparatus utilizing gravity and buoyancy principles have been developed which claim that they can be utilized to generate a larger out-put than in-put. However, such devices have proven to be only theoretical andthus do not have practical use for the claimed purpose.

However, the present invention provides a method and apparatus which is practically utilizable as a separate source of power generation.

OBJECTS AND SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a practical apparatus for generating power utilizing gravitation force and buoyancy.

Another object of the present invention is to provide a power generating apparatus which is both simple in application to other devices such as generators and is low in manufacturing cost.

A further object of the present invention is to provide a power generating apparatus which comprises two cylinders and two float members disposed in the cylinders, respectively, the float members having respective weight members disposed thereon,whereby the out-put force resulting from the action of the float members moving up and down can be utilized with other known apparatus such as a generator by converting rotational motion to rectilinear motion or rectilinear motion to rotational motion.

Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and specific examples, whileindicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detaileddescription.

The present invention relates to an apparatus for the generation of power which comprises a first cylinder and a second cylinder, a first float member and a second float member disposed in the first and second cylinders, respectively, the floatmembers including corrugated air bags therein, a weight member disposed on the float member, an inlet and outlet for introducing and removing a fluid, i.e., water, into and out of the first and second cylinders and an inlet and outlet for introducing andremoving air into and out of the first and second float members, whereby when the fluid and air are introduced into the first cylinder and first float member and simultaneously removed from the second cylinder and second float member, the first floatmember is caused to rise in the first cylinder and the second float member is caused to fall in the second cylinder. Thus, the weight member disposed on the float member causes the floating member containing the corrugated section to be compressed.

DETAILED DESCRIPTION OF THE INVENTION

Referring now in detail to the drawings for the purpose of illustrating the present invention, the power generating apparatus of the present invention as shown in FIG. 1 comprises a first cylinder 10 and a second cylinder 30, of an upper endopen-type, a first float member 11 and a second float member 31 disposed in the first and second cylinders 10 and 30, respectively, a first inner cylinder 12 and a second inner cylinder 32 disposed in the first and second float members 11 and 31, a firstweight member 22 and a second weight member 42 disposed on the top of the first and second float members 11 and 31. The uppers of cylinders 10 and 30 are provided with water supply pipes 15 and 35 which are connected to a water supply tank 50. Thefloat members 11 and 31 can vertically float within the cylinders 10 and 30 when the spaces 13 and 33 between the float members and float members are filled by the water. Solenoid-type water supply valves 25 and 45 are located in the water supply pipes15 and 35, respectively. Also, the bottoms of the cylinders 10 and 31 are linked with water drainage pipes 16 and 36, respectively, through a solenoid-type valve 73. The pipes 16 and 36 are also connected to water drainage tank 51 through pipes 26 and46 and a common pipe 53. Pipes 26 and 46 are each provided with separate valves 27 and 47, respectively (see FIGS. 5, 6 and 7). The water drainage tank 51 is equipped with a water pump 55 through a motor M and the pump is connected to the water supplytank 50 with a hose or pipe 54. As shown in FIGS. 2A, 2B and 3, the first and second float members 11 and 31, the lower part of which is made of a flexible material such as plastic or rubber, are provided with connecting axis members 21, 41, air inlets17, 37, and air outlets 18, 38. A plurality of side guide-rollers 19, 39 are mounted at the upper of the floating members, and a plurality of bottom guide-rollers 20, 40 are mounted at the bottom thereof. The float members 11, 31 contain corrugatedportions 28, 48 disposed at the lower ends thereof so that the floating members 11 and 31 can vertically extend within the cylinders 10 and 30 when the spaces 14, 34 between the float members and inner cylinders 12, 32 are filled by the air. The weightmembers 22, 42 are mounted to the axis 21, 41 by nuts 23, 43 (FIG. 3). The weight of the weight members 22, 42 can be controlled in proportion to the size of the radius of the float members 11, 31 and the height of the cylinders 10, 30. For example,when the radius of the float members are 25 cm and the height of the cylinders are 100 cm, the weight of the weight members are 88.76 ft.lb., but, if the radius of the float members are increased to 50 cm and the height of the cylinders to 200 cm, theweight of the weight members are increased to 1,420.20 ft.lb., thus increases in linear.

The air inlets 17, 37 are connected to air storage tank 59 through solenoid-type valves 75, 76 as shown in FIGS. 2A and 2B. The air storage tank 59 is provided with a pressure gauge 60 for controlling the pressure therein. The motors M, M1 areconnected to an ampere gauge 69 to know the energy in-put.

The air outlets 18, 38 which vent to the atmosphere for discharging the air are provided with solenoid-type valves 77, 78 for control purposes. An air compressor 56 having a pressure gauge 74 and the motor M1 is provided with an air hose 57which is connected to each solenoid-type valve 25, 27, 35, 47, 73, 75, 76, 77 and 78 for activating on/off switches (FIG. 4). The air used in the solenoid-type valves is stored in the air storage tank 59 through a hose 58 for subsequent use by thefloating members 11 and 31.

As shown in FIGS. 1 and 8, the axis members 21 and 41 are connected to one end of "L"-shaped levers 61a, 61b through connecting members 79a and 79b and the other end of the levers 61a, 61b are connected to one end of crank arms 63a, 63b. Theother end of the crank arms 63a, 63b are connected to a crank 64 by crank pins 66a, 66b of the crank arms 63a, 63b to both side tracks 65a, 65b of the crank 64. The crank 64 having a crank shaft 80 can be connected to a generator 67 or the like througha belt 68. The generator 67 is provided with an ampere gauge 69 for displaying the energy out-put. The "L"-shaped levers 61a, 61b include a pivot pin 62 fixed to a stand member (not shown).

In operation, as shown in FIGS. 1, 5 and 8, the water supply valve 45 is opened to supply to the second cylinder 30 and the air inlet valve 76 is opened to supply to the second float member 31. Simultaneously, after closing the horizontal valve73 and valve 47, the drainage valve 27 is opened to drain the first cylinder 10 and the air outlet valve 77 is opened to vent the air from the first floating member 11. The second float member 31 within the second cylinder 30 is then raised due tobuoyancy force and air filling the corrugated section 48 to its highest point while the first float member 11 is lowered to its lowest position by gravitational force. The weight member 22 on the first floating member 11 assists the gravitational forceand when the water in the first cylinder 10 and air in the first float member 11 are empty, the first floating member 11 falls very fast. Accordingly, when the first float member 11 falls, the "L"-shaped lever 61a reaches a descended position and, asthe second float member 31 rises, the "L"-shaped lever 61b reaches a raised position. Accordingly, when the crank arm 63a is attached to track 65a by the pin 66a on one side of the crank 64, the other crank arm 63b is attached to track 65b by the pin66b on the other side of the crank 64. The pins 66a and 66b are separated from each other 180° on the crank 64.

When the apparatus is positioned as shown in FIG. 5, the water supply valve 45 is closed, the drainage valve 27 is also closed and at the same time the horizontal valve 73 is open. Simultaneously, the air inlet valve 76 of the second floatmember 31 and the air outlet valve 77 of the first float member 11 are closed. At the same time, the air outlet valve 78 of the second float member 31 and the air inlet valve 75 of the first float member 11 are opened. The water contained in thecylinder 30 then flows naturally to the first cylinder 10 through the pipes 16 and 36 and, thereby, the two float members 11 and 31 are positioned at the same height which is equivalent to one-half of the height of the cylinders (FIG. 6). As the watermoves from the second cylinder to the first cylinder, the "L"-shaped levers 61a and 61b assume equivalent positions. Accordingly, the crank 64 rotates 90° in the clockwise direction and the crank pins 66a and 66b are positioned opposite eachother in the crank tracks 65a and 65b.

The opposite operation as shown in FIGS. 1, 7 and 8, comprises simultaneously, in succession, closing the water supply valve 45, closing the horizontal valve 73 and opening the drainage valve 47 and at the same time, closing the drainage valve 27and opening the water supply valve 25. Simultaneously, in succession, the air valves 76 and 77 are closed and the air valves 75 and 78 are opened. Accordingly, the "L"-shaped lever 61a connected to the first float member 11 changes its position and, asthe second float member 31 is lowered, the "L"-shaped lever 61b reaches a descended position. Accordingly, the crank 64 rotates 90° in the clockwise direction and the crank pins 66a and 66b are positioned at opposite portions on the crank tracks65, 180° from each other. In this operation, microswitches 70 are disposed at the lower and upper ends of the levers 61a, 61b for operating the on/off switch when the levers 61a and 61b reach their lower and upper positions.

By repeating this series of steps an increased out-put force can be obtained from the "L"-shaped levers 61a and 61b.

One of the important features of the subject invention is believed to be the clearance between the float member and cylinder and, taking into consideration the water level in which the first and second float members 11 and 31 is immersed. Also,the expansion force of the air in the float assists in lifting the weight member on the float.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious toone skilled in the art are intended to be included in the scope of the following claims.
